Method Detail

apply

boolean apply(long first,
            Object second)

Applies a procedure to two arguments. Optionally can return a boolean flag to inform the object calling the procedure.

Example: forEach() methods often use procedure objects. To signal to a forEach() method whether iteration should continue normally or terminate (because for example a matching element has been found), a procedure can return false to indicate termination and true to indicate continuation.

Parameters:

first - first argument passed to the procedure.

second - second argument passed to the procedure.

Returns:

a flag to inform the object calling the procedure.
